Bishop denies WA Liberal vote will dive

West Australia was the strongest state for the Liberal Party at the last federal election but three seats are now considered under threat.

Deputy leader Julie Bishop visited one of them, Swan, on Friday.

Local MP Steve Irons was introduced as her "good friend and a champion for the electorate", which is nominally held by seven per cent but Labor believes it is a strong chance of winning it back.

Ms Bishop was announcing $3 million in funding for the Wirrpanda Foundation, which provides programs for young indigenous people and is run by indigenous footballer David Wirrpanda, and $10 million for the West Coast Eagles' $65 million new Lathlain Park training facilities.

She was the second high-ranking federal government minister to visit the riverside seat for the week, following WA MP and Justice Minister Michael Keenan's appearance to announce $20 million of rehab services for the drug methamphetamine, from a $300 million national funding pool.

She rejected any suggestion the Liberals were likely to lose three out of the 12 seats it holds in WA to Labor.
